Mobile draining station for motor vehicles

ABSTRACT

A mobile draining station for motor vehicles is disclosed, comprising a container ( 1 ) whose side wall and upper wall can be lifted up and in which carrier arms ( 6 ) for receiving a vehicle are arranged in a stationary manner; pivoting arms ( 13 ) for removal devices pivotably connected to the rear wall ( 7 ) of the container; and at least one door element ( 8 ) which is embodied in the rear wall ( 7 ) and which can be folded out downwards in order to extend the base of the container. Collectors ( 10 ) are positioned in the container in the region in front of the door element. Said collectors can move through the door opening onto the folded-down door element.

The invention relates to a mobile draining station for motor vehicles which are to be scrapped or otherwise disposed of.

It is the object of the invention to provided a draining station which is compact for transporting and provides sufficient working area in the operating mode.

This is solved according to the invention essentially by the features of claim 1. Because wall parts of the container can be lifted up and collectors for the liquids to be removed can be moved out of the container, there results in the operating mode of the mobile draining station a working area undisturbed by collectors.

FIG. 1 shows a perspective representation of a container 1 having the standard dimensions for a container provided for the transport of goods. On the front end a receiving bracket 2 is provided on a carrier mount 3 so that for transport, the container can be received onto a loading area by means of a crane vehicle or the like.

In the embodiment shown in FIG. 2, the front side wall 4 of the container can be lifted up together with the upper wall 5, so that the side wall 4 forms a roof area. In the container 1, two carrier arms 6 for the vehicle to be drained are arranged in a stationary manner approximately in the middle of the rear wall 7. In FIG. 2 these carrier arms 6 are only indicated schematically. In the operating mode according to FIG. 2, a vehicle for draining is set down on the carrier arms 6 by means of a forklift truck or a corresponding lifting means, and removed again after draining.

According to another embodiment, the upper wall 5 is lifted slightly by means of a crank equipped with a safety spring, whereupon a roof extension consisting of three parts is folded outwards and fixed. Hereby, stiffening elements can be provided, such as an inclined strut between the roof area and the rear wall.

In such an embodiment, instead of a crank having a safety spring, a hydraulic cylinder can also be provided on both sides of the container for lifting the roof. In FIG. 3, a safety rod 4 a is arranged between the roof and the container base for supporting the roof. Such a safety rod can be omitted if actuation is by hydraulic cylinders.

On both sides of the carrier arms 6, in the rear wall 7 door elements 8 a and 8 b are formed which can be folded out downwards by means of a hinge along the base wall 9, as shown in FIG. 3. In the transport position according to FIG. 1, in front of the door elements 8 a and 8 b there are positioned in the container 1 large-volume collectors 10 which, in the operating position according to FIGS. 2 and 3, are moved towards the folded-away door elements 8 a and 8 b as shown schematically in FIG. 3, so that the working area in the container is cleared. To allow a large number of vehicles to be drained by the mobile draining station, large-volume collectors 10 are provided which have a corresponding capacity if the different liquids from a large number of motor vehicles are to be received. In the embodiment shown, four collectors 10 for petrol, diesel, used oil and coolant are provided, wherein the individual containers can also have a different capacity.

The collectors 10 can be moved onto the base 9 of the container 1 on rails 11 as shown schematically in FIG. 2. This rails 11 are also provided on the door elements 8 a and 8 b, as shown schematically in FIG. 3, so that the collectors 10 can be moved onto the folded-down door elements.

The door elements 8 are coupled to the base wall of the container such that in the opened state they are aligned with the base wall 9 of the container. On the outer ends of the door elements, means for height adjustment are mounted so that on uneven ground the folded-out door elements can be fixed in a horizontal position. Exemplarily, spindles 8 c having a support plate can be provided on the door elements and adjusted by torsion to the corresponding height, wherein they are supported on the base by means of the support plates.

FIG. 4 a shows two of the collectors 10 in the position inside the container with the folded-down door element 8. FIG. 4 b shows the collector 10 displaced outwards onto the folded-down door element. Filling pipes 14 and hoses for an overflow safety device are flexibly mounted on the collectors 10 and laid such that they make it possible to displace the collectors without dismounting the pipes. Two pipe angles of a wall fastening 15 are directed into the inside of the container. The pipes 14 a and 14 b (in FIG. 4 the second pipe is covered by the first one in each case) are designed as flexible rubber hoses. A connection angle piece of rigid pipes 16, which preferably consist of galvanized steel tubes, are also directed into the inside. The pipe angles of the wall fastening 15 are arranged higher than the angles pieces of the rigid pipes 16 on the collectors to allow unhindered displacing thereof.

The plant is equipped with a pneumatic overflow safety device for monitoring the collectors. These overflow safety devices each have an optical and an acoustic display, which is not shown in detail.

Between the collectors 10 and the rails 11, a safety device is provided for each position of the collectors. Preferably, a laterally flattened shaft is provided for this, which is carried in the base wall 9 of the container and rotatable by 90°.

Further, in the container 1 several removal devices are provided which are explained in detail below. The power supply for these removal devices, such as pumps and suction means, is provided by means of a compressed-air connection 12 mounted on the container 1, to which an external compressor can be connected. From the central compressed-air connection 12 indicated schematically in FIG. 2, pipes (not shown) lead to the individual removal devices for operating thereof.

In the whole working area, special grates are provided on the base 9 of the container.

Instead of an external power supply which can also be designed as an electric power supply, a drive aggregate such as a compressor or an electricity-generating device can also be provided inside the container 1 and is transported to the service locations together with the container 1. Preferably, in such a case the power supply aggregate at the container can also be moved out, corresponding to the collectors 10 which can be moved out, so that the working area in the container 1 is not blocked.

Under the carrier arms 6, pivoting arms 13 for funnels and similar removal devices are pivotably mounted on the rear wall 7 of the container or on a column. Manually operated removal devices such as brake hose nippers are preferably also mounted on the rear wall 7 of the container with corresponding hose connections so that they can be taken down, allowing the operator to work under the vehicle which is supported on the carrier arms 6.

To fix the pivoting arms 13 during transport, a fixing rail, shown in FIG. 5, can be pivotably coupled to the rear wall of the container. FIG. 5 a shows a side view of the fixing rail 17 coupled by means of a hinge 17 a to the rear wall 7 of the container in the open state, while FIG. 5 b shows a side view of the fixing rail 17 in the closed state. FIG. 5 c shows a front view of the closed fixing rail 17 which is fixed on the one pivoting arm 13 a by means of a locking pin 17 b having a split-pin 17 c and by means of a lateral opening overlaps the other pivoting arm 13 b so that this is also fixed in position during transport.

According to another embodiment, the pivoting arms 13 a and 13 b can be fixed by means of a clamping device to a linkage of bars which during transport is anchored to the collectors 10, for example to their dome covers.

A tank boring device is provided in the container for allowing the removal of fuel from the tank of a vehicle if this should not be possible or expedient by using a tank suction hose. FIG. 6 shows mounted on a support 18 a boring apparatus 19 which is displaced upwards by actuating a foot pedal 25, wherein simultaneously a lever for a compressed-air motor mounted on the boring apparatus can be actuated. In FIG. 6, K indicates a motor vehicle. FIG. 7 shows a view of the boring apparatus 19 having a connection pipe 19 a for the compressed-air motor. A vacuum pipe 19 b is connected to a valve 19 c which can be opened after boring the tank so that the fuel can be drawn off via the suction pipe 19 b.

In FIG. 7, a compensator 20 for an electric potential is connected to a conducting part of the motor vehicle before drawing-off, and is removed again after drawing-off. After drawing-off of the fuel, the opening drilled into the tank is closed by a plug.

The tank boring device 19 is placed under the tank of the vehicle by a pivoting arm 13. At the lower end of the column 18 for the boring device 19, an eccentric disc 21 having a rotation axis 21 a is mounted which can be rotated using a lever 21 b having a hand knob 21 c such that the whole device can be lifted from the base or lowered onto it. Supporting this eccentric disc 21 on the base results in good stability during boring upwards into the tank. By releasing the eccentric lever 21 b, the upper part of the boring device is lifted, preferably supported by a gas pressure spring (not shown), up to the base of the vehicle tank.

FIG. 9 shows a fuel control valve 22 connected to the suction pipe 19 b of the boring device and allowing to separate petrol and diesel. A hand lever 22 a actuates a three-way valve mounted in the housing of the control valve 22 so that the fuel is fed from an inlet 22 b to which the suction hose 19 b is joined, according to the position of the lever to the outlet 22 c or 22 d leading to a petrol pump or diesel pump (not shown) through which the fuel is pumped into the respective collectors 10.

FIG. 10 shows a gear housing boring device 23 which is used for speed-changing gears and differential gears with no drain plugs. This gear housing boring device 23 has a drill having a special ground section and a correspondingly strong compressed air motor for drive. This gear housing boring device 23 is provided moveably on a support 23 a in the container 1. Height adjustment takes place by means of a gas pressure spring (not shown).

To prevent the penetrating of the wall of the gear housing such that the hardened toothed wheels of the gear are hit, the bore depth of the gear boring device 23 is limited. For this, on the lower end of the column 23 a a hand spindle 24 (FIG. 12) is attached, in which an inner thread is provided. With this hand spindle 24 the moving distance of a foot pedal 25 (FIG. 12) can be adjusted to the required bore depth. In FIG. 11, an adjusting rod 24 a has an outer thread 24 b. This adjusting rod 24 a is rigidly mounted on a base plate (not shown) of the gear boring device. An adjusting screw 24 c has a counternut 24 d with which the minimum bore depth is set.

Using the foot pedal 25 shown in FIG. 12, the boring device is displaced upwards along the whole bore distance. This applies to the tank boring device 19 and the gear boring device 23. By pressure on a tread 25 a, a pressure plate 26 of a fork 25 b of the foot pedal is displaced upwards. The foot pedal is supported on a rocker joint 25 c. The rocker joint 25 c is screwed to the base plate of the boring device or to a base foot in the case of a pivoting arm design. The pressure plate 26 is rigidly joined to the slide rod or the support 18 or 23 a of the boring device.

For varying the bore depth, instead of the hand spindle 24 another attachment can be provided on the boring device. FIG. 13 shows a basic attachment 27 having a horizontal groove 27 a throughout which allows the unhindered escape of resulting bore chips. Distance attachments 27 b′-27 b″ have different heights and are used according to different gear housing walls. For example, the distance attachment 27 b″ is used for cast iron material, attachment 27 b′ for aluminium, and attachment 27 b for sheet steel. The bore chuck is designated by 27 c.

During removal of the fuel from the tank, a plurality of sieve devices removes a considerable number of dirt particles from the fuel while it is still in the tank boring device 19, wherein the subsequent filtering of petrol and diesel in front of the pump opening takes place separately.

Further, in the container 1 there is quality control for recognizing and separating clean petrol and impure substances. FIG. 14 shows mounted in the container 1 a glass cylinder 28 in which a filling tube 29 is arranged such that it just ends at the base of the glass cylinder to avoid foaming of the liquid. The filling tube 29 is joined at 28 a to the delivery side of a pump (not shown). A control amount tube 30 determines by its height the amount of medium to be checked. If the position of a lever 31 is disregarded, the quality control is designed such that the overflow amount is fed directly into the collector for impure substances. The lever 31 is joined by a linkage of bars 31 a to two valves 32 a and 32 b. The outlet for impure substances is designated by 33. FIG. 14 a shows the different positions of the lever 31. In the upper middle position, impure fuel is fed to the drain 33. By displacing the lever or the two valves, the fuel can be let off either through the outlet 32 b for clean petrol or through the outlet 33. By this process, simultaneously an opening 34 for emptying of residue is opened, which is located directly on the base of the cylinder 28 for quality control. In the petrol pump pipe to the collector 10 there is a built-in flame guard filter for excluding the possibility of an explosion.

To remove used oil after opening the drain plug on the oil pan of a vehicle, the funnels 35 a and 35 b are provided in FIG. 15 for catching used oil from the gear and engine. A holder 36 is provided on one of the funnels for storing the drain plugs. The distance between the two funnels can be adjusted, after opening a locking screw 37, by displacing the bars 37 a and b such that optimum positioning of the funnels under the drain plugs of gear and engine is guaranteed. By actuating the levers of valves 38 a and 38 b, the path to the pump is opened or closed. A pneumatic lifting means 39 between two guide rods 40 a and 40 b of a linkage of bars carrying the funnels allows vertical displacement of the funnels so that these can be placed directly at the gear or the engine, to achieve a short dropping height of the used oil. The guide rods 40 form a parallelogram so that during lifting and lowering, a parallel course of the guide rods takes place. A rocking lever 41 and a compressed air limiter 42 actuate the compressed air cylinder 39. The lower guide rod 40 b has a forked bend at 40 c, which does not hinder the movement of the compressed air cylinder 39. The linkage of bars is designed such that the horizontal movement is guided by means of two joints when the funnels are positioned in the required position. A prestressed cap 43 and a friction disk 44 at one of the joints have the function of a brake so that the set position of the funnels is maintained. By tightening the prestressed cap 43, increased pinching of the friction disk 44 is achieved for increasing the braking effect.

On the gear housing boring device 23, one side of the threeway valve 23 b, an additional suction pipe 23 c is connected, by means of which hydraulic fluid can be drawn off.

For drawing off brake fluid, in the container 1 a brake hose nipper 45 is provided as shown in FIG. 16. The clamping jaws 45 a and 45 b are formed such that they can receive all conventional hose sizes. On the lower clamping jaw 45 b a cutter 46 is provided, in which a bore 46 a is formed for drawing off brake fluid from the brake hose. A tight fit of the nippers can be achieved by means of an adjusting screw 45 c. The nippers are closed by pressing their tension lever 45 d, wherein the cutter 46 cuts open the brake hose. The nippers can be reopened by means of a release lever 45 e. On the lower clamping jaw 45 b a connecting nipple 45 f is provided, to which a suction hose is joined. FIG. 16 a shows in detail the cutter 46 in two views rotated by 90°.

FIG. 17 shows a suction pistol 47 which allows the removal of oil from the power steering and the automatic gears without cutting the hoses. On the suction pistol 47, a bracket 48 is mounted for surrounding the hose. After surrounding the hose, a lance 47 a is displaced forwards whose tip 47 b is placed on the hose. The tip 47 b can be formed as a triangle so that it can also be used for hoses with steel fabric. At the tip there are openings 47 c for drawing off the liquid. For the forward displacement of the lance 47 a, a conventional forward feed pistol having an actuating lever 47 d is used. The forward displacement path is limited such that the bore comes to abut on the lance tip inside the hose walls. An adjusting screw 47 e is provided for adjusting the length of the lance. Joined to the lance there is a hose 47 f through which the drawn-off liquid is let off.

In the container 1, pumps (not shown in detail) are provided for the drawing-off processes. Further, in the container a shock absorber boring device is installed preferably on the rear wall 7. For brake fluid, provided stationarily in the container there is a vacuum tank which has a smaller volume than the collectors 10 and can thus be arranged in a stationary manner in the container. The same applies for a vacuum tank for windscreen anti-freezing agent.
